time 类

 1 timeStamp = time.time()  #获取当前的时间戳
 2 print(timeStamp)
 3 # 1555555453.6283455
 4 
 5 timeTuple = time.localtime(timeStamp)  #时间戳 --> 时间元组
 6 print(timeTuple)
 7 # time.struct_time(tm_year=2019, tm_mon=4, tm_mday=18, tm_hour=10, tm_min=46, tm_sec=25, tm_wday=3, tm_yday=108, tm_isdst=0)
 8 
 9 timeStr = time.strftime('%Y-%m-%d %H:%M:%S', timeTuple)  #时间元组 --> 字符串
10 print(timeStr)
11 # 2019-04-18 10:48:33
12 
13 new_timeTuple = time.strptime(timeStr, '%Y-%m-%d %H:%M:%S')  #字符串 --> 时间元组
14 print(new_timeTuple)
15 # time.struct_time(tm_year=2019, tm_mon=4, tm_mday=18, tm_hour=10, tm_min=51, tm_sec=40, tm_wday=3, tm_yday=108, tm_isdst=-1)
16 
17 new_timeStamp = time.mktime(new_timeTuple)      #时间元组  --> 时间戳
18 print(new_timeStamp)
19 # 1555555984.0
